 from .models import Brand

 class ABCView(APIView):
   def post(self, request,format=None):
    report = Brand.objects.all()
    template_path = 'profile_brand_report.html'

    response = HttpResponse(content_type='application/pdf')
    response['Content-Disposition'] = 'attachment; filename="Report.pdf"'

    context = {'report': report}
    template = get_template(template_path)
    html = template.render(Context(context))
    print (html)

    pisaStatus = pisa.CreatePDF(html, dest=response)

    return response

I hope work this

def generate_pdf(data):
    buffer = BytesIO()
    p = canvas.Canvas(buffer, pagesize=letter)
    for row, item in enumerate(data):
        for col, value in enumerate(item.values()):
            p.drawString(col * 100 + 20, row * 30 + 20, str(value).encode('utf-8'))

    p.showPage()
    p.save()
    buffer.seek(0)
    pdf_output = buffer.getvalue()
    buffer.close()
    return pdf_output

We don't need to use a class based view for it. For simplicity we can use a function based view. Change your code as below.

from django.template.loader import render_to_string

def generate_pdf(request):
    report = Brand.objects.all()
    template_path = 'profile_brand_report.html'

    response = HttpResponse(content_type='application/pdf')
    response['Content-Disposition'] = 'attachment; filename="Report.pdf"'

    html = render_to_string(template_path, {'report': report})
    print (html)

    pisaStatus = pisa.CreatePDF(html, dest=response)

    return response

We can also use wkhtmltopdf to generate PDF's in django.
